Description

technical field

[0001] The invention relates to a heat engine, in particular to a regenerator assembly for a heat engine. Background technique

[0002] The heat engine regenerator is a key component of the heat engine circulation system and one of the key components that directly affects the performance of the heat engine. The regenerator is installed between the heater and the cooler, and its function is to store and release heat energy: when the working fluid moves from the heating tube to the cooler, part of the heat energy in the working fluid is absorbed by the regenerator when passing through the regenerator , so that the temperature of the working fluid can drop from the highest temperature of the cycle; and when the working fluid moves from the cooler to the heating tube in the second half of the cycle, and passes through the regenerator again, the regenerator returns the heat energy to the working fluid, so that The working fluid out of the regenerator gets energy ...

Embodiment Construction

[0027] Figure 1-4 Shown is an embodiment of the present invention, the regenerator assembly 2 is installed inside the regenerator cylinder 1, and a cooler 3 is installed at the lower end, which is composed of an outer sleeve 21 and a wire mesh weldment, and the wire mesh weldment is built in Inside the outer sleeve 21. The wire mesh welding part is composed of a wire mesh welding part 1 22 and a wire mesh welding part 23, and may also be composed of a plurality of wire mesh welding parts. The wire mesh component is stacked with multi-layer wire mesh and then sintered by diffusion welding. The wire mesh is generally made of stainless steel, and the wire mesh of 200-250 mesh is mostly used. The larger the mesh number, the denser the heat recovery effect is, but the greater the flow resistance is, so the regenerator needs to be considered comprehensively in the design The type of wire mesh is selected according to the heat recovery capacity and resistance requirements of the c...
